Review: *update* not working - My dog had fleas since September and sounded like a seasonal problem because I had him adopted only 7 months ago. He is flea free now after used the first dose 3 weeks ago. *update* I had combed off the fleas while using this product but I found fleas on my dog again… the product might have killed the fleas for once but won’t protect him afterward.
Review: Works for a couple weeks - My dogs seem fine for a couple of weeks then they are fending off flies again!

### ⭐⭐⭐⭐ Works for a couple weeks
*by E***Y on 22 June 2019*

My dogs seem fine for a couple of weeks then they are fending off flies again!

### ⭐⭐⭐⭐⭐ Worked Quickly and Perfectly
*by W***E on 18 April 2021*

When I adopted my pup he was completely overridden with ticks. Engorged ticks. Tick nests. It was horrible. I applied this in the evening and in 24 hours the ticks were GONE. It's been weeks and 0 ticks. It was an easy application, just squeeze it onto his shoulder area. I was amazed at how quickly it worked and how well it worked. Affordable also! (We live in an area without fleas so I can't speak for flea effectiveness. )
